Samsung Electronics and LG Electronics will display ultra-HD TVs with curved screens that measure 105 inches diagonally in Las Vegas next month, they said Thursday.

LG's 105UB9 model is 105-inch (measured diagonally) 21:9 aspect ratio CURVED ULTRA HD TV. LG says the TV offers magnificent picture quality and a wide viewing angle. It boasts an 11 million pixel (5120 x 2160) screen resolution and has been developed in collaboration between LG Electronics and LG Display. In order to realize the TV's curvature, new technology was introduced to resolve a number of issues, such as maintaining structural integrity and delivering uniform color and brightness across such a large screen. Until now, OLED panels were preferred for curved displays due to their ability to generate their own light. LG's new curved TV uses an LCD display instead, which is typically easiter and cheaper to develop. However, LG Display claims it overcame the challenge of uneven backlighting of LCDs by refining its Thin Film Transistor (TFT) pixel circuit technology to prevent color leakage.

Samsung's curved 105-inch curved UHD TV adopts a new proprietary picture quality algorithm that delivers optimized color and greater feeling of depth, according to Samsung. It is based on an upgraded curved LCD panel and packs new TV circuit technology.

The 105" Curved UHD TV provides almost two times vivid images when viewed from the side and the also "the best possible TV viewing experience from any angle". Also, the 105 incher adopts 'Quadmatic Picture Engine' which delivers all content in UHD-level picture quality no matter what the source is. Samsung's 105-inch Curved UHD TV boasts an 11 million pixels (5120X2160) screen resolution with a 21:9 aspect ratio.

The two South Korean consumer tech giants have already launched 55-inch curved TVs, though the rollout was seen as more of a marketing ploy. Samsung and LG were eventually forced to sell the TVs at discounts after limited consumer interest.

The companies haven't disclosed when the 105-inch curved TVs will be available on the market.

This year's first batch of curved TVs featured next-generation organic-light-emitting-diode screens. But the pricing proved prohibitive because OLED screens are more expensive to mass produce in larger sizes.

Now, both 105-inch models use of more affordable LCDs.

Both Samsung and LG kept mum on prices. But Samsung's current 85-inch Ultra HD display is priced at $40,000, while LG has a 84-inch Ultra HD display priced at $17,000.

LG also plans to announce its first WebOS-based Smart TV at CES. The television will include a 2.2GHz dual-core processor and 1.5GB of RAM, according to LG researcher Hong Sung-pyo, who speaked at an event in Korea on Thursday.

Earlier this year, LG announced that it had acquired WebOS from HP. But unlike its predecessors, LG said it had no plans to bundle it with mobile, deciding instead that it might be a suitable option for HDTVs.
